I can definitely sympathize... I'm trying to make a similar choice. I feel like a lot of people are trying to make this decision, and it sucks, because now both schools have the same Second Look weekend. To be honest, I liked Vanderbilt a lot more, but I think it was more a function of how the schools handled interview day than it was the actual schools.
Here's my take: quality of education and availability of resources at both schools are excellent. I think that, for most people, if you'd be happy at one, you'd be happy at the other. That's why waiting for financial aid information to come through is your best bet. Other than that, here are a few other differences I've gathered:
- Both have excellent dual degree options, but they offer different ones, and some are more popular than others. For the MD/MPH, Pitt has an excellent school of public health, while Vandy's is a little bit more limited. If you're interested in an MD/JD, Vanderbilt has the better law school. For an MBA, I think both schools are comparable. There's a whole array of other dual degree options unique to each school.
- The weather's nicers in TN, but you'll definitely need a car in Nashville. Pittsburgh is more walkable/public transportation-accessible, IMHO.
- Cost of living is almost exactly the same.
- Class size at Pitt is slightly larger (~150 vs. ~100 at Vandy).
- One of the complaints I heard at Pitt was about its financial aid (or lack thereof), and Vandy is known for its merit scholarships. Could just depend on the person, though. FWIW, average indebtedness at Pitt is about $20,000 more than at Vanderbilt, and Pitt is technically a state school. Go figure.
- Pitt offers PSTP and CSTP, which are five-year programs that integrate a year of research. Yes, it's an additional year in school, but the research year, you get a stipend ($10,000 or so). Five lucky students in each program don't have to pay a dime to go to med school, while three get a three-year scholarship. Pretty nice deal, if you're into clinical research.
- In terms of access to cool facilities, Pitt has the simulation center, while Vanderbilt has that fabulous new children's hospital.
- Students at both are pretty friendly and down-to-earth. The students at Vandy seemed a bit more laid-back/less stressed, but I only met a few students at Pitt. Vanderbilt does boast about its incredibly high student satisfaction, and I can believe it.
- As mentioned earlier, there's the Emphasis Program at Vandy. I happen to really like the idea of research automatically integrated into the curriculum, so for me, that's a plus.
Overall, a final decision between the two would probaby have more to do with your preferred setting, atmosphere, and your particular interests within medicine, than anything related to quality of education or opportunities. Good luck with the wait list. At the very least, no matter how this process turns out in the end, you'll still end up at a great school!
